Ubuntu – nother way to restart the sound system if pulseaudio/ALSA don’t work

alsapulseaudio

I was listening to music, and my sound suddenly went dead in all my applications. I'm using Ubuntu 12.04, which uses pulseaudio, so I tried sudo /etc/init.d/pulseaudio restart, but nothing happened. According to lsof | grep pcm, nothing is using the soundcard at the moment, although I'm not entirely sure if my source for that command is applicable.

Is there a way another way to restart Ubuntu 12.04's sound system from the command line without rebooting the system?

  • I've used pulseaudio -k && sudo alsa force-reload a couple of times, and it worked well. The first part kills pulseaudio, the second reloads ALSA. You don't need to restart pulseaudio, because it auto-restarts.
